Weirdly, I took a load out to the Alps with me and out there they were awesome and they continued to be awesome when I got back. Obviously this led me to buy some more which have done nothing but squeal and resist any attempt to make me slow down.

I got through a set in two days of alpine riding. They haven't lasted much longer in wintery UK conditions either. Quiet and powerful though, I'm temped to save them for summer in case that's when they prove a little more durable.
